A dust mite allergy is actually a hyper-sensitivity reaction to proteins found in the feces of dust mites. These proteins may attack the respiratory airways causing mild to severe allergic reactions and even asthma. House dust mites are found most homes around the world.
Microscopic Dust Mites
Dust mites are microscopic organisms that thrive in warm and humid environments such as furniture and bedding materials. Their favorite food is human skin flakes and animal dander. Since human actually shed thousand of skin flakes everyday and dogs, cats and other household pets shed dander daily, dust mites never run out of food.
As we inhale large quantities of dust mite protein allergens, the body produces antibodies in the form of a chemical compound known as histamine. Histamine is what causes an allergic reaction and can lead to swelling and irritation of the upper respiratory passages. It is believed that dust mites allergies are one of the primary causes of childhood asthma symptoms and the predisposition for this allergy is often hereditary.
Unlike pollen, dust mites are present all year round causing constant allergic reactions. The excretion from the mites dries out and can become airborne when someone walks over a rug, sits down in a chair or shakes the bed clothes, creating immediate symptoms in allergic people.
Controlling Dust Mites
The best tool controlling these microscopic dust mites is the HEPA (High Efficient Particle Air) vacuum. The certified HEPA vacuum cleaner (or central vacuum system) is the best dust, skin flakes and dust mite removing device over which you have total control. You decide what surfaces you vacuum and when. Any other vacuum filter is potentially a vacuum polluter and only recycles the microscopic dust which can be responsible for many respiratory allergies and asthma.
